Maybe more than that Leslie if you got ahold of a new factory spring somehow. Mine is flattened out some I'm sure. Another problem you will run into if you go with a double or triple spring is the channel sides the spring fits in is only long enough to capture one 1/4 or 3/8" thickness of spring. And there is only one bolt holding the spring on. A second hole has to be added up through the bottom of the channel to hold the second (lower) spring in place. Not that hard to do when you have a trap door like mine does, but I'm guessing you don't have that added feature. JImChuk

Here's something funny...I joked earlier about the current wheel being a shopping cart wheel....I think it actually is!!! Looking at replacements for it and the only thing that seems to meet the specs and design is actually a shopping card wheel.

I was amazed and delighted at how Dean kept the costs down and made it easier for "ordinary folks" to build his plane - had a good chuckle when he said he cut strips out of a milk jug to make hanger bearings for the flaperons. The cable trailing edge was a money-saver too, although a better trailing edge can be made from the aluminum ones that Spruce sells. The cable brakes were another money-saver that needed upgrading too, so I guess a shopping cart tailwheel would be a cheaper way to build as well. EDMO

I would not be too concerned about slightly raising the tail. I can't see the entire spring on your photo but it look rather short and with a 5 in wheel you might currently be lower than many others. True, if you have shopping chart wheel on the main gear... well...

I do agree with previous comments, pneumatic is definitely the way to go. So is double spring...

Actually I recall once doing that on an UL years ago replacing it's t/w. I had a shopping cart stashed in the back of the hanger that I found on the side of the road. Those wheels are damn good and w/sealed bearings.

That's the one. I called them 5 years ago and they knew exactly what I needed. They even shipped it before they had cash in hand (I mailed them a check). Great folks. 1 1/4" wide, fits fine in the slot of the Model C with one bolt and renders the perfect angle for the Maule assy.

I took my spring off and went to a car spring shop, they rebent it in 5 minutes and did it for $20.

The tail wheel is at station 147.5 on my MK IV, so that every 2.6 inches is a degree (one inch per 57 inches is a degree).

I went from the 6" Maule to the 8" Matco (pneumatic, single arm) and I guess I am now a degree or so lower angle at tail touch than before, but the full stall 3 pointers are just as easy as ever, and the landings are softer, the taxiing is noiseless and easy to steer, and I love the new tailwheel.
